Radiation levels south of the reactors have leveled off. For example, radiation levels in the Tsukuba-Tsuchiura area, about 100 miles of the reactors, have been stable for several weeks, and are essentially at normal levels.
http://rcwww.kek.jp/norm/Farmers in southern Ibaraki, 70 miles and farther south of the reactors*, have been planting their fields, as they always do at this time of year.
All produce grown in Ibaraki Prefecture, on the southern boundary of Fukushima Prefecture, has been deemed safe for consumption, with the possible exception of spinach.
Tourism in Ibaraki Prefecture during the recent week-long holiday period declined dramatically compared to last year. For example, attendance at Hitachi Seaside Park, which is one of the big tourist attractions of Ibaraki that is about 60 miles south of the reactors, was said to be only about 25% of what it was last year at this time. Tourism at Mount Tsukuba, another popular Ibaraki destination, is off by even more than that.
The prevailing winds in the reactor area are blowing from the SE, so the areas to the immediate NW of the reactors are in deep doodoo right now. But Iwaki City, to the immediate south, is not in bad shape-- for the time being.
Small fish caught off the coasts of Fukushima and Ibaraki prefectures have been detected with relatively high levels of radiation, and there are therefore prohibitions against their sale.
Large fish that eat these smaller fish and migrate southward have been caught off the coast of Choshi/Kashima, a little more than 100 miles south of the reactors. The national government claims the radiation levels are safe in these big fish, but I was talking to a man last night who said he is not going to be eating fish for a while "because fish aren't supposed to be radioactive". There seems to be increasing interest in beef, and I have noticed more beef from the US and Australia being sold in local Ibaraki grocery stores.
*The 70-mile figure is the extent of my personal observations, and information I have obtained from Ibaraki residents. I'm sure that fields north of that area are also being planted as in regular years.
